steel shim head gasket
What's everyone's opinion about the rubber coated steel shim .015 head gasket? Has anyone had any problems with sealing? Any info would be great, thanks!

I'll add a twist to stfinney's question. The '51-'53 331 Chrysler Hemi gasket sets come with a bare steel shim gasket, no coating at all. How do you get these to seal, even with the typical copper gasket spray?
Note to 331 Hemi owners; I use composition 354 gaskets on my 331. Only modification needed is to silicone in little filler tabs of gasket material in the parts of the teardrop shaped pushrod holes that stick outside the head/block joint.

I've used two different products with success. Permatex Copper"Spray-a-gasket" and a product called Hylomar. Both in aerosol form. Spray an even coating on both sides of the gasket and install while still tacky (about 10 minutes)

The stock 305 SBC that I got had those steel shim types on it. Think it came out of a 87 Blazor. Didnt look like it had been leaking I dont see how either. <img src="confused.gif" border="0">

Dead soft copper, or as they say it is, will seal a head rather well. Allthough they are prone to leaks if the head and deck aren't PERFECTLY flat. There a little more geared for "off road" racing however.

i'd say if you can afford it get it. it's worth a half a compression point or so.
